Hmmm. Lightweight AGM Battery For CPAP?
Just musing possibilities. Can't have everything - light weight, amp hours, thick plates and low price. But the 'lil sister versions of this critter may be interesting as an overnight CPAP power so...

I mostly see sealed lead acid batteries at the battery outlet. I guess a motorcycle Grp battery is fairly common AGM. I have a few small AGM's, 40AH and less. They were made by Deka-Penn, The Pure Lead Enersys brand. They were bought used but are holding their own in the last five years. I'd estimate a 30 AH AGM weighs in just shy of 20 lbs.
